7.1 Common Commands
Common commands are described in the IEEE 488.2 (IEC 625-2) standard. These com-
mands have the same effect on different devices. The headers of these commands con-
sist of "*" followed by three letters. Many common commands are related to the status
reporting system.
Some of the commands in the following list are R&S CMW500-specific but use the same
syntax as common commands. They are marked "not IEEE 488.2-confirmed".
For commands related to macros see chapter 7.3.1, "Macro Commands", on page 196.
